Mixing it Up

y-tail-xenos

There are all sorts of things I would like to know, but never take the time to learn - so much stuff, so little time... So I figure that some stuff will just have to wait until I need it. Such is the case of just how you mechanize a V-tail. You have two surfaces doing the work of three on a conventional tail - two ruddervators instead of two elevators and a rudder.

The ruddervators work like elevators in that they move up and down to control pitch - but they also move more in one direction than the other when the pilot pushes a rudder pedal. The two surfaces effectively "mix" the inputs from both pitch and yaw controls. Sounds complicated, right? So... how exactly is this done?

Look Ma - No Wings!

Something changed radically in the shop this past week - a milestone came and passed - and so did those huge long wings for the Xenos! Notice the workbench? No wings! With the help of a lot of airpark neighbors, we had a marathon month of drilling, deburring, and riveting, and the long motor glider wings are now tucked safely in their racks, awaiting installation in the fuselage - which now comes back to center stage as we pull out the drawings and figure out where we left off.

One Down - One to Go!

Xenos wing

All has not been quiet in ye 'olde aeroplane factory since we got back from AirVenture. With another kit coming in late September, and the shop fully up and running, it was time to get moving on the wings for the Xenos, and the result is now a finished left lifting surface, with the right framework ready to go on the workbench to get its skin in the next couple of weeks! No, we have no intention of finishing up the motor glider before the little jet arrives, but it would be nice to have the majority of the metal work done so that it's "just" a matter of systems work and over-all integration. You know -the last 90% or so... Continue reading "One Down - One to Go!"

Only One Way to Skin This Wing

There may be more than one way to skin a feline (I've never tired), but if you stray from the instructions while skinning this wing, you're going to drill yourself into a corner! The process for drilling the skin to these long Xenos wings is one of the few step-by-step procedures given in the plans, and the number of parts and the way they overlap and allow/block access means that following the steps is well advised.

A Whole 'lotta Ribs!

Xenos-Motorglider-wing-ribs

Yup - that's a lot of ribs for one wing, isn't it? Finally, after a long delay building a new shop, we got back to work on our Xenos Motorglider project. Sitting behind me as I took this picture was our RV-3, noteworthy because it has just about the same wingspan tip-to-tip as this single wing for the Xenos. Like I said - a lot of ribs!
